    Repurposing sewage and toilet systems: environmental, public health, and person-centered healthcare applications
    (Wiley, 2024) Bonventre, Joseph; Özcan, Aydoğan; Department of Mechanical Engineering; Department of Mechanical Engineering; Yığcı, Defne; Taşoğlu, Savaş; Koç University Research Center for Translational Medicine (KUTTAM) / Koç Üniversitesi Translasyonel Tıp Araştırma Merkezi (KUTTAM); KU Arçelik Research Center for Creative Industries (KUAR) / KU Arçelik Yaratıcı Endüstriler Uygulama ve Araştırma Merkezi (KUAR); School of Medicine; College of Engineering
    Global terrestrial water supplies are rapidly depleting due to the consequences of climate change. Water scarcity results in an inevitable compromise of safe hygiene and sanitation practices, leading to the transmission of water-borne infectious diseases, and the preventable deaths of over 800.000 people each year. Moreover, almost 500 million people lack access to toilets and sanitation systems. Ecosystems are estimated to be contaminated by 6.2 million tons of nitrogenous products from human wastewater management practices. It is therefore imperative to transform toilet and sewage systems to promote equitable access to water and sanitation, improve public health, conserve water, and protect ecosystems. Here, the integration of emerging technologies in toilet and sewage networks to repurpose toilet and wastewater systems is reviewed. Potential applications of these systems to develop sustainable solutions to environmental challenges, promote public health, and advance person-centered healthcare are discussed. The integration of emerging technologies in toilet and sewage networks can repurpose toilet and wastewater systems and facilitate the development of sustainable solutions to global issues. Here, environmental, public-health related, and person-centered healthcare applications of repurposed toilet and sewage networks are reviewed. Potential challenges in implementation and future directions are discussed. image

    Scalable low-power skyrmionic logic gate library
    (Wiley, 2024) Department of Electrical and Electronics Engineering; Department of Electrical and Electronics Engineering; Cheghabouri, Arash Mousavi; Yağan, Rawana; Onbaşlı, Mehmet Cengiz; Graduate School of Sciences and Engineering; College of Engineering
    Magnetic skyrmions, despite being promising ultra-low energy information carriers with wide bandwidth and nonvolatility, are not used for any universal scalable logic system. Here, a detailed understanding of skyrmion motion in nanowires under different geometries and drive conditions is established. Then, these insights are used to introduce a general Boolean-universal gate block system with components, emulation, and simulation algorithms. The resulting system can collectively form a scalable, cascadable, and universal skyrmion logic system and produce arbitrary logic designs. The NOR, AND, OR, NAND, XNOR, and FULL ADDER gates are provided here as example demonstrations of the system. The toolkit lays the foundation for bridging the gap between theoretical exploration and practical implementation of skyrmion-based computing. The skyrmion block components may help reduce energy consumption per logic operation after eliminating Joule heating. The insights and designs may help skyrmions be used in state-of-the-art electronic design automation. Magnetic skyrmions emerge as revolutionary information carriers in this Boolean-universal gate block system, promising a leap in computational efficiency. With innovative emulation and simulation, this work demonstrates essential logic element like NOR and FULL ADDER. This breakthrough shortens the space between the theory and application, paving the way for advanced spintronics design automation with reduced energy demands.
